- *
- * This thumbnail caching implementation attempts to conform
- * to the Thumbnail Managing Standard proposed on freedesktop.org
- * The standard is documented here: \n
- * https://www.freedesktop.org/wiki/Specifications/thumbnails/ \n
- *
- * This code attempts to conform to version 0.7.0 of the standard.
- *
- * Notes:
- * > Validation of the thumb's embedded uri is a simple strcmp between our
- * > version of the escaped uri and the thumb's escaped uri. But not all uri
- * > escape functions escape the same set of chars, comparing the unescaped
- * > versions may be more accurate. \n
- * > Only Thumb::URI and Thumb::MTime are stored in a thumb at this time.
- * Storing the Size, Width, Height should probably be implemented.
